For the fitness enthusiast who wants to track health stats without wearing a bulky smartwatch, the BIEMHA waterproof smart ring offers a sleek alternative. It's perfect for monitoring sleep and daily activity while you're at the gym, in the pool, or at the office.
Unlike a wristband, this ring is barely noticeable—you can wear it all day and night without it getting in the way. The automatic heart rate monitoring captures your resting rate while you sleep, and the sleep tracking breaks down light, deep, and REM stages. You'll see exactly how your workouts affect your recovery.
Thinking about taking it for a swim? No problem. The 80-meter waterproof rating means you can wear it in the ocean or lap pool. With a 2-3 day battery life that extends to over a week with the charging case, and no subscription fees, you get complete health insights without recurring costs. Compatible with both iOS and Android.
